A student observed liquid wax dripping down the side of a burning candle. After putting out the candle's flame, the student left the room. Several hours later the student observed that there was no longer any liquid on the side of the candle. Which statement explains what MOST LIKELY happened to the liquid wax?

• The heat given off by the flame caused the candle wax to evaporate.

• The liquid wax changed back into a solid as it cooled.

• The liquid wax was condensed and absorbed by the candle.

• The liquid wax was changed from a solid to a liquid.

Students learn that the volume of an object depends on the amount of space the object takes up. Based on this information, which of the following objects has the least volume?

• tennis ball

• soccer ball

• basketball

• beach ball

Which statement BEST describes what happens as water changes from one state to another?

• As water is cooled, it freezes and changes from a solid to a liquid.

• As water is heated, it evaporates and changes from a liquid to a solid.

• As water is cooled, it condenses and changes from a gas to a liquid.

• As water is heated, it melts and changes from a gas to a solid.

A student is creating a collection of objects that are magnetic. Which items do not belong in his collection?

• paper clip

• plastic beads

• iron shavings

• steel ball bearings

• aluminum can

A student uses a triple beam balance to measure the mass of an ice cube. The student records the mass of the ice cube as 7 grams. The student then allows the ice cube to melt and measures the mass of the melted ice cube. What was the mass of the ice cube after it melted?

• 0 grams

• 6 grams

• 7 grams

• 8 grams

A student conducted an investigation about density. The materials used were water, liquid A, a cork, and a grape. The results of the investigation are shown. Objects Water Liquid A Cork oats oats grape sinks oats Which option shows the correct order of the materials from highest to lowest density?

• cork, grape, water, liquid A

• water, liquid A, cork, grape

• water, cork, liquid A, grape

• liquid A, grape, water, cork

(a)  

Part B: The best statement to support answer A is ​that as ice-cream is heated ​ ​ it melts and changes from a solid to a liquid (b)  

• The ice cream will stay the same.

• The ice cream will melt.
• The ice cream will turn into a gas.

• it melts and changes from a solid to a liquid
• it condenses and changes from a gas to a liquid
•  it evaporates and changes to liquid
